JDSU Introduces Smallest Widely Tunable Transmitter Optical Subassembly

JDSU introduced a widely tunable transmitter optical subassembly (TOSA) for the DWDM transceiver market. The new TOSA brings full band tunability, or the ability for service providers to change to any wavelength on demand, to pluggable small form factor (XFP) transceivers that previously only supported one to two wavelengths. The pluggable small form factor can also be used in products that support 50GHz channel spacing.




JDSU said its new TOSA represents a dramatic reduction in size and cost compared to previous discrete solutions for tunable transmitters.


The TOSA houses JDSU's Integrated Laser Mach Zehnder (ILMZ) chip that was announced in September 2007. The ILMZ is a photonic integrated circuit (PIC) that combines a tunable laser and optical modulator on a tiny chip for smaller, higher performance tunable solutions. JDSU produces the ILMZ using a semiconductor style of manufacturing that allows this functionally integrated optical solution to be produced in high volumes more quickly and efficiently, resulting in lower costs.http://www.jdsu.com
